Article Abstract

When the result of a significance test is reported, present practice is to state the exact significance level reached. This implies that either a finely graduated table of significance levels exists and/or an interpolation procedure is available. The motivation for this practice is based on the idea that there is a fair difference between significance values reached of say, 0.015 and 0.045. Yet if a table giving just the 0.05 and 0.045. Yet if a table giving just the 0.05 and 0.01 points is available, the only statement that can be made is that both results were significant at the 0.05 level.
